Question

What is the recursive formula for this sequence 12,16,20,24,28

Answer 1

I think it’s 12 table I believe

Answer 2

The recursive formula is

`a_n = a_ {n - 1}+ 4`

Step-by-step explanation

The given sequence is 12,16,20,24,28

The first term of this sequence is

`a_1=12`

The common difference is

d=16-12

d=4

The recursive formula is given by

`a_n = a_ {n - 1}+ d`

So we need to substitute the known values to get

`a_n = a_ {n - 1}+ 4`
